to ppm" or "ppm to mg/m
The conversion equation is based on 25 ºC and 1 atmosphere:
X ppm = (Y mg/m
= (X ppm)(molecular weight)/24.45
Fill in either the "ppm" value (X) or the "mg/m
" value (Y) AND the molecular weight of the compound. Then press the "Calculate" button.
based on the molecular weight of
